Column Security Level in SharePoint
there are some existing and new options that will achieve the same results. In the end, you are wanting to keep users from viewing or changing columns... you can:
- Use the new capabilities of InfoPath to customize the web forms
(.aspx): for read-only or hidden
- Use the new capabilities that give lists RELATIONAL capability to do
